Single-photon three-dimensional imaging at up to 10 kilometers range
Abstract
Depth and intensity profiling of targets at a range of up to 10 km is demonstratedusing time-of-flight time-correlated single-photon counting technique. The system compriseda pulsed laser source at 1550 nm wavelength, a monostatic scanning transceiver and a single-elementInGaAs/InPsingle-photonavalanchediode(SPAD)detector.High-resolutionthree-dimensional images of various targets acquired over ranges between 800 metres and 10.5 km demonstratelong-rangedepthandintensityprofiling,featureextractionandthepotentialfortargetrecognition.Usingatotalvariationrestorationoptimizationalgorithm,theacquisitiontime necessary for each pixel could be reduced by at least a factor of ten compared to a pixel-wiseimageprocessingapproach.Kilometerrangedepthprofilesarereconstructedwithaverage signal returns of less than one photon per pixel.
